WMA to JAR Converter
Processing entirely on your device — large files may take a moment.
Repack a JAR as ZIP to inspect classes and resources with any unzip tool. If your files are still in WMA format, this page is the shortcut: WMA is Microsoft’s Windows Media audio format, still found in old music collections and voice recorders.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the WMA format
WMA (Windows Media Audio) is Microsoft's MP3 competitor from 1999, best known for DRM-protected download stores in the 2000s. The family spans standard lossy WMA, WMA Pro (up to 24-bit/96 kHz) and WMA Lossless. On Windows it integrated seamlessly; everywhere else it required goodwill.
With Microsoft's own services having moved to AAC, WMA today is a conversion source: old music libraries and ripped CDs get converted to MP3/M4A/FLAC and the format is retired. WMA Lossless files should go to FLAC to preserve their losslessness.
+Strengths
- ✓Native Windows playback and tagging
- ✓WMA Lossless preserves bit-perfect audio
!Limitations
- −Non-Windows support is poor
- −Ecosystem abandoned by its creator
- −DRM-legacy files may be unplayable
About the JAR format
A JAR is a ZIP with Java manners: class files, a MANIFEST.MF, resources and optional signatures. Any tool that opens ZIPs can open it — but converting to a plain ZIP strips the “is this executable?” ambiguity and makes browsing the contents painless.
Useful for auditing dependencies, extracting embedded resources, or checking what a library actually ships before adding it to a build.
+Strengths
- ✓Standard Java delivery format
- ✓ZIP-based, tools abound
- ✓May carry signatures and manifests
!Limitations
- −Not a installer — just a package
- −Contents are class files, not source

Frequently asked questions
Is this WMA to JAR converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for WMA to JAR?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
Can I convert a whole folder of WMA files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
